Foreword This Technical Specification (TS) has been produced by ETSI Technical Committee Integrated broadband cable telecommunication networks (CABLE). This present

4、document produced for the transition technologies accommodates an urgent need in the industry to define requirements that enable seemless transition of Cable Networks to IPv6. Considering the depletion of IPv4 addresses, transition to IPv6 is required in order to enable continued growth of the custo

High-quality connectivity to all kinds of IP-based services and networks is essential in todayls business and private life. A plethora of transition technologies have been proposed in IETF, other stand

Each of these technology options is specified, implemented and deployed in various forms and stages. The present document is based on the requirem
